This kit offers versatility that creates exciting options for performers and teachers. You can mix and match your rims or stay with one rim size and build a kit that has multiple cup depths. Choose a backbore for versatility and pair it with a commercial backbore for when you need that extra zip or perhaps a cornet or piccolo trumpet backbore.

Yes, you can have the kit made with acrylic tops (available in clear or teal only and orders will be fulfilled with available color/stock) for $15 more.

TOPS:

1 Series mouthpieces: Inner Diameter .684

1B: Similar to the Papa this mouthpiece has a medium large b-shaped bowl, and slightly smaller backbore.

1C: This is my take on an older Bach 1C but with an improved throat and backbore combo. It feels significantly more efficient and sounds more energized while maintaining a rich core throughout all registers. This mouthpiece has our standard 24 throat and 10/24 combo backbore.
1CS: A new product for this line this piece is smilar to the 1C except it's slightly smaller and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak". I particularly like the fact I can get plenty of assistance on this piece and still a very large, orchestral sound.
1 Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you!I designed this mouthpiece to feel more forgiving (especially in this blank) and gained more core in the overall sound shape. This mouthpiece is a weapon for the commercial trumpet player!

1 ¼ series: Inner Diameter .675

1 ¼ BC: This has a classic Bach Mt. Vernon 1-1/4C mouthpiece rim that's blended in the CAD program with a great old Bach 5B cup. The result is an incredibly rich sounding mouthpiece without losing efficiency or having the turbulent points caused by a traditional "screw-rim" setup. This comes standard in our Traditional blank. Completely re-designed for this line in 2023 the results are amazing!

1 ¼ C: This is a take on a great 1 1/4C mouthpiece with some refinements in bore, backbore, and throat. To me it feels more like a 1.5C due to the great efficiency.

1 ¼ CS: Similar to the 1.25C except it's slightly smaller and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak".
1 ¼ Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you!I designed this mouthpiece to feel more forgiving (especially in this blank) and gained more core in the overall sound shape. This mouthpiece is a weapon for the commercial trumpet player!

1 ½ Series: Inner Diameter .668

1 ½ BC: This has a classic Bach Mt. Vernon 1-½ C mouthpiece rim that's blended in the CAD program with a great old Bach 5B cup. The result is an incredibly rich sounding mouthpiece without losing efficiency or having the turbulent points caused by a traditional "screw-rim" setup. This comes standard in our Traditional blank. We have re-engineered this mouthpiece in 2023 and it’s amazing!

1 ½ C: This is one of my best-selling mouthpieces and extremely comfortable compared to other manufacturers' "cookie cutter" rim contoured 1 1/2's.
1 ½ CS: Similar to the 1 1/2C except it's slightly smaller and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak".
1 ½ Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack.

2 Series rim (based on our ACB MV3C rim): Inner Diameter .664

2BC: A new product in this new line the concept is similar in to other BC cups in our line. This 2 (old MV3C) mouthpiece rim that's blended in the CAD program with a great old Bach 5B cup. The result is an incredibly rich sounding mouthpiece without losing efficiency or having the turbulent points caused by a traditional "screw-rim" setup. This comes standard in our Traditional blank. Again this is an all-new mouthpiece in 2023 and it’s amazing!

2C: This is our most popular mouthpiece in the line, the MV3C, re-named for this new line (and we are adding pieces around this supremely popular setup). Another special mouthpiece!
2CS: MV3C rim with my CS cup -- it's slightly smaller and also has a much more efficient entrance into the throat. This helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak."

3 Series mouthpieces: Inner Diameter .654

3B: Same rim as on my 3C but with a medium deep B-shaped bowl. It's one of my most popular mouthpieces and has an incredibly warm tone!

3C: My take on a fantastic Bach 3C mouthpiece from the late 60's; I have never played a 3C like it. I think the added mass and proper matching backbore make this a formidable all-around mouthpiece!

3CS: Similar to the 3C except it's slightly smaller and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak".
3 Studio: This piece actually was one of the inspirations for the new line. This piece is now super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you!I designed this mouthpiece to feel more forgiving (especially in this blank) and gained more core in the overall sound shape. This mouthpiece is a weapon for the commercial trumpet player!

This helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak."

5 Series mouthpieces: Inner Diameter .644

5B: My modernized take on one of the finest mouthpieces ever made, the Bach New York 5B. I've made the ACB 5B mouthpiece much more efficient than the vintage counterpart while maintaining the great sound shape and spread. It's one of my most popular sizes.

5C: Long considered a transitional mouthpiece for the student, I've spent a bunch on time on this piece as most of my earlier prototypes didn't make the cut. This mouthpiece has an incredibly rich tone with fantastic articulations and ease in all registers. It's a great, comfortable mouthpiece!
5CS: all new for 2023 this is the 5 rim with my CS cup (newly designed for 2023!) -- it's slightly smaller and also has a much more efficient entrance into the throat. This helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak."
5Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you! I designed this mouthpiece to feel more forgiving and way more efficient than other options we have had in this rim diameter previously. I recently used this mouthpiece playing assistant Principal with the St. Louis Symphony for all of their “lead trumpet” needs and it did not disappoint!

7PT for Piccolo Trumpet: Inner Diameter .640

Desinged for Piccolo trumpet with a shallow cup (similar to a Bach 7E)

TA1 Series: Inner Diameter .635

TA1: A modified version of Clark Terry's very flat rim, made more comfortable and accessible with the high point pulled out slightly. Medium V-cup designed for a rich, flexible tone.

TA1B: : It has a cup design using our super popular B cup (based off a great playing NY Bach 5B cup and then blended with my cad program to eliminate any turbulence this is a great piece for someone who wants a full, rich sound but not a large diameter. This is a new offering in the line and comes in the Traditional blank.
TA1 CS: Similar to the TA1 in cup volume except it's bowl shaped and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak". This is offered in the Standard blank.

TA-Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you!

10 ½ series mouthpieces: Inner Diameter .628

10 1/2C: While this is a fairly small diameter mouthpiece it produces a big tone, with a fine high register and resonating low register. I started with this piece thinking it would a good mouthpiece for students to start on, but I find it very good for all players, especially those with very thin lips and ones who want a bit more corner support.

10 ½ CS: Another new piece in the line this is similar to the 10 1/2C in cup volume except it's bowl shaped and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak". This is offered in the Standard blank.
10 ½ DS: Another new piece in the line this is similar to the 10 1/2S in cup volume except it's even more aggressive in terms of the cup volume, throat blend, backbore shape, and efficiency. This is a fabulous lead and commercial piece. This is offered in the Standard blank

10 ½ Studio: This is another new option in the line and is super popular as a crossover mouthpiece. Tons of "zip" and front to the attack. A special all-new cup, throat, and backbore produces one of the most efficient commercial pieces I have played without it backing up on you!I designed this mouthpiece to feel more forgiving (especially in this blank) and gained more core in the overall sound shape. This mouthpiece is a weapon for the commercial trumpet player!

BACKBORES:

ACB backbores are designed to be as acoustically efficient as possible. Currently I have many different tapers available!

Here are our standard backbores, from high compression commercial backbores to wide-open orchestral backbores:

KA3: Our newest commercial backbore and it is amazing! Feels almost like the throat is one size smaller due to the compression.
KA2: A very nice backbore with good zing.
KA1: More core than the A2 and a bit tighter as well.
A2: The A2 is a weapon! Designed to be mated with compression mouthpieces.
T (Tight): commercial backbore which provides the most resistance and "zing" to your sound
MT (Medium Tight): Provides great resistance, especially for players who tend to "backup."
S (Standard): Provides the best balance between resistance and sound spread for most players.
MO (Medium Open): A great slightly open symphonic shape produces a rich, warm tone but still gives ample resistance when needed.
A1: This backbore is a very large, symphonic backbore that is in between the MO and O – a wonderful backbore suited for the classical player or jazz soloist wishing for a large sound!
AOS: Designed for C trumpet players looking for a large and warm sound, it's open and free-blowing. It provides a feel and sound spread that is perfect for orchestral playing and for chamber music.
AK: Open taper that produces a huge, resonant, and warm symphonic tone. Based on the classic Tottle backbores famously played by orchestral players for decades.
O (Open): This is a very large, open backbore designed for the orchestral musician to provide the feel and sound spread that most orchestral players prefer
OO (Very Open): Huge backbore for enormous, rich sound (takes a lot of air)
